The number ofsashes 4 of the series may be as desired and by way of example but twosashes are shown. 'I'he sashes 4 are pivoted at their sides to the framesides I, 2 as at 5. The top and the sill of frame 3 are indicated at 8,1, respectively.

The sash opening and closing operator 8 is common to and functions tosimultaneously open and close the sashes 4. The operator 8` will includesuperposed spaced sash opening and closing mechanisms 9 of like formcorresponding in number to the number of sashes 4. Each of saidmechanisms will include a pair of aligned spaced sections I0, IIconnected to a sash 4 and with the section Ill being spring controlled.The sections III and II are'connected tothe frame sides I, 2,

respectively.

The frame side I below the pivots i for a sash 4 is formed with anopening I2 having arranged therein and extended from the ends thereof abushing or bearing I3. Mounted on the ends of the bushing or bearing I3are inner and outer apertured spacer plates I4 iixedly secured to side Iby the oppositely disposed holdfast means I5. The frame side 2 below thepivots 5 for a sash 4 is formed with an opening I6 whichaligns with theopening I2. Arranged in and having its ends extended from the opening I6is a bushing or bearing I1. Mounted on the ends of the bushing I1 areinner and outer apertured spacer plates I8 iixedly secured to side 2.Vby the oppositely disposed holdfast devices I9.

The section I0 is what may be termed a. sash holding means andl includesa rotatable stub shaft 20 mounted in and extending from each end of thebushing I3. Positioned on the reduced o'uter end of shaft 20 and bearingagainst the outer spacing plate I4. is the apertured inner terminal partof a lifting and lowering bar 2I for a sash 4. The said apertured innerterminal part ofthe bar 2I is secured on the outer end of shaftv 20 bythe holdfast means 2 I. The bar 2l consists of inner and outer end parts22, 23, respectively, and an intermediate part 24 arranged between, atan an? gle to and for disposing the parts 22, 23 in offset relation,that is to say, positioning said parts 22, 23 in parallel planes. Thepart 23 has its outer end arranged between andpivoted as at 25 to theouter ends of a pair of spaced parallel links 26. The inner ends of thelinks 26 are pivotally connected, as at 21 to a coupler 28 secured tothe rear face oi one side stile of a sash 4. The inner pair of spacedparallel links 4I.

end'of shaft 201s formed with a head 29 bearing against the inner spacerplate I8 and provided with a crank arm 30 having a hook 3| at its outerend. Secured to the frame side I above the shaft 2D is an eye 32.Arranged between the hook 3| and eye 32 is a coiled controlling spring33 having one end attached to the hook 3| and its other end to the eye32. The springs 33 function as controlling means for the mechanisms 9for counterbalancing the weight of the sashes 4 and also as a latchingmeans for the mechanisms 9 for holding them when adjusted and suchadjustment will be presently referred to.

The section II is what may be termed a sash shifting structure andincludes a rotatable stub shaft 34 mounted in and extending from eachend, of the bushing |1. Positioned on the reduced outer end of the shaft34 and bearing against the outer spacing plate I8 is the apertured innerterminal portion of a lifting and lowering bar 35 for that sash 4 towhich the bar 2| is coupled. 'I'he said apertured terminal part of bar35 is secured on'the end of shaft 34 by the holdfast means 36. The bar35 consists of inner and outer end portions 31, 38, respectively and anintermediate portion 39 between, at an angle to and for disposing theportions 31, 38 in offset relation, that is to say, positioning saidportions 31, 38 in parallel planes. The portion 38 has its outer endarranged between andpivotally connected, as at 49 to the outer ends of aThe inner ends of the links 4| are pivotally connected, as at 42 to acoupler 43 secured to the rear face of the other side stile of the sash4. The couplers on the side stiles of the sash 4 are arranged in spacedalignment, are of like form and each consists, with reference to Figure1, of a plate 44 anchored by the holdfast means 45 (Figure 2) to thesash and formed with ashank 46 which extends between a pair of links andto which the inner ends of the latter are pivotally connected. Thelifting arms 2|, 35 are oppositely disposed.

The section II includes the providing of the inner end of shaft 34 witha head 41 which bears against the inner spacing plate I8 and is formedwith a crank arm 48 having secured to its outer end, as at 49 anactuating member 50 of linklike form pivotally connected, as at I to oneof the couplers 52 of a plurality of superposed spaced couplers formingparts of a vertically movable carrier structure 53 which forms anelement of the operator 8.

'I'he carrier structure 53 will include spaced superposed couplers 52corresponding in number to the number of opening and closing mechanisms9. The carrier structure 53 not only includes the couplers 52, but alsoa vertical tube 54 of a length less than the height of the window frameand which is arranged in the frame side 2. The upper portion of innerface of the tube 54 is formed with threads 55. Arranged within the tube54 below the threads 55 is a bushing 56. The tube 54 is providedintermediate its ends and lengthwise thereof with an elongated slot 51.The bushing 56 is also formed with a slot 58 which registers with theslot 51. There is correlated with the tube 55 a stationary combinedguide and arrester element 59 which functions to guide the tube 54 andalso prevents the revolving of the tube on its vertical axis, as well asprevents the bushing 56 revolving relative to the tube 54. The element59 is arranged in the frame side 2 and includes a base 68 which isfixedly secured by the holdfast means 6| to the inner face of the bodyof frame side 2. Formed integral with the base 68 is a shank 62 whichmerges into a collar 63 encompassing the tube 54. The collar 63 is ofmaterially less length than the slots 51, 58 and has its inner faceformed with a key 64 extended in to the said slots 51, 58 to arrest theturning of tube 54 on the vertical movement of the latter. The collar 83constitutes a guide for tube 54. Each coupler 52 surrounds the tube 54,is secured to the latter by the holdfast means 65 and has a portion 66extended towards the sash 4. The portion 66 has extending therethrough aheaded pivot bolt 61 connected to said portions 66 by the nut 68. 'Ihebolt 61 forms the pivot for the actuating member 50.

The operator 8 includes an operating mechanism 69 for the carrierstructure 53. The mechanism 69 consists of a rotatable verticallydisposed elongated shaft 10 which extends through and is of greaterlength than the tube 54. Arranged within the lower portion of frame side2 is a stationary gear box 1|. Journalled in the gear boxI 1|, as wellas extending rearwardly from frame side 2 is a rotatable shaft 12 havingfixed thereto a bevel gear 13 disposed in the box 1|. The rear end ofshaft 12 is provided with a crank handle 14 for the purpose of rotatingthe shaft 12. The shaft 10 extends into the box 1| and is provided onits lower end with a bevel gear 15 which permanently meshes with thegear 13.

Arranged on the top of box 1| and interposed between a collar 15 onshaft`10 and box 1| is a bearing means 16. The top 6 of frame side 2,within the latter has a depending inverted yokeshaped member 11 (onlyhalf of which is shown). The bight 18 of member 11 has secured to thelower face a bearing means 19 for correlation with a beveled bearingenlargement at the upper end of shaft 10. The latter in proximity to itsupper end is formed with peripherial threads 8| for coaction with thethreads 55 on the inner face of the tube 54 to provide for the elevatingof the latter on the clockwise movement of shaft 10 to open the windowsashes and for the lowering of the tube 54 on the anti-clockwisemovement of the latter to close the window sashes. The opening movementof the window sashes is had against the action of the springs 33. Whenthe tube 54 is moved upwardly, the couplers 52 of the carrier 53 willact on the sections |I of the mechanisms 9 to provide for such sectionsI| to lift open the window sashes and these in turn will actuate thesections I0 of the mechanisms 9 against the action of the springs 33.These latter, at the end of the desired extent of the upward movement oftube 54 will act to latch the threads 55, 8| whereby the Window sasheswill be latched on their adjusted open position, and they also act tolatch the window sashes closed.

With reference to the structure shown by Figure 5, it illustrates amodified form of sash operator, in accordance with this invention foradaptation with a window 82 having two parallel sets of window sashes83, 84. The window as shown consists of two like parallel sections 85one for each set of sashes. Each section will consist of an outer and aninner side frame member. The inner side frame member indicated at 86 iscommon to both sections. The outer side frame members of the sections ofthe frame are not shown, but each will accord in structure to the sidemember heretofore referred to. In the modified form the sashes of oneset will laterally align with the sashes of the other set to form pairsof aligned sashes. Each of the aligned sashes of a pair has correlatedtherewith a sash opening and closing mechanisms 8 of the form referredto. The sections i of the mechanisms 8 are not shown, but the sectionsIi are and are indicated generally at 81, 88, Figure and eachcorresponds in all particulars with respect to their structuralarrangement to section III of mechanism 8. 'Ihe sections 81, 88 are oflike form and correspond in construction to the section Il, but areoppositely disposed. The sashes, 84 will be arranged in the sections 86,pivotally supported from the outer side frame members and from the innerside frame member 88. The modified form shown by Figure 5 includes acarrier 88 of the same form as the carrier 88 with this exception, thatthe couplers 80 of the carrier 88 will have the sections 81, 88 of themechanisms 9 pivotally connected to opposite sides thereof as at 9i. Thecarrier 88 is arranged in the inner side frame member 88. The saidsections 81, 88 of the mechanisms 8 will be pivotally supported byopposed walls of the inner side frame member 86. The operating means 82for the carrier 89 is arranged within andv extended from the inner sideframe member 86. The means 82 corresponds in structure to the means 88.Otherwise than that as stated the modified form shown by Figure 5 andgenerally indicated at 83 will be of the same construction as the formsash operator shown by Figure 1. The form 88 is employed forsimultaneously opening and closing a pair of laterally aligned spacedwindow sashes, or simultaneously opening and closing superposed pairs oflaterally aligned spaced window sashes.

Although the sashes are shown as being shiftably supported from thepivots 5, yet it is to be understood that they may be hinged in lieu ofbeing pivoted.
